IMPROVEMENT m VENTlLATOR-REGlS T ERS.

Specification forming part of Letters Patent No. 154,387, dated August25, 1874; application filed August 1, 1874.

To all whom it may concern:

Be it known that I, HENRY A. GOUGE, of the city, county, and State ofNew York, have invented a new and useful Improvement inVentilator-Register, of which the followingis a specification:

Figure 1 is a front view of my improved register, showing in dottedlines the position of the openings, the valve, and the posts. Fig. 2 isa detail vertical section of the same, taken through the line 00 m, Fig.1.

Similar letters of reference indicate corresponding parts My inventionhas for its object to furnish an improved ventilator-register, whichwill allow the air to enter the ventilating-flue in a body, instead ofbeing broken up into small streams, as is the case when the ordinaryregister is used, so that it may enter the flue in a compact current.

The invention consists in the combination of the posts having a rightscrew-thread upon one end, and a left screw-thread upon the other end,the nuts at each end, and the locknuts, with the front plate, and theflue, provided with a weighted valve and a balancecord, as hereinafterfully described.

A is a branch flue leading into the main flue, and which is designed tobe set in the wall, or otherwise secured to said flue. The outer end ofthe flue A is provided with a narrow outwardlyprojecting flange, a, tooverlap the wall around the opening in which said flue A is set. B isthe front plate of the register, which is made without any openingthroughjit, and the outer surface of which may be made plain, or may beornamented, if desired. 0 are four posts, which have right screw-threadsout upon one end, and left screw-threads out upon their other ends. Theouter ends of the posts 0 screw into nuts or short bars c,secured to thefront plate B, which plate may be made double, to cover and conceal thebars or nuts 0 The inner ends of the posts 0 pass through holes in theflange a of the flue A, and screw into nuts 0 placed upon the inner sideof said flange a, and kept from turning by resting against the side ofthe flue A, or by other convenient means. The inner ends of the posts 0should have slight heads formed upon them to guard against their beingaccidentally screwed out of the nuts 0 Upon the posts 0, upon the outeror forward side of the flange a, are placed lock-nuts 0 which, by beingturned up against the flange a, prevent the posts 0 from getting out ofplace when adjusted. D is the valve, which is hinged at its lower edgeto the lower side of the flue A, and to the inner side of its upper partis attached a weight, d to lower the said valve when released. The valveD may be provided with small springs d to prevent it from being drawn sofar forward that the weight (1 will not open it. 7

The same thing maybe accomplished by making the valve seat with a slightinward inclination.

To the upper part of the valve D is attached a cord, E, which passesthrough a guide-eye, or over a guide-pulley, F, attached tothe upperpart of the inner side of the frontv plate B, The cord E extendsdownward, and hangs in such a position thatit may be convenientlyreached to adjust the valve D. To the lower end of the cord E isattached a weight or a weighted tassel, e, to balance the weighted valveD d so that the said valve will stay in any position into which it maybe adjusted.

If desired, the lower end of the cord E may be secured to abelaying-cleat or other convenient device. The flue A is built into orotherwise secured to the wall or main flue with the posts 0 attached toit.

To attach the front plate B, the posts 0 are screwed out as far aspossible, and the said plate B placed upon their outer ends. Then, byturning the posts 0, they will be screwed at the same time into the nuts0 0 When the plate B is brought to the desired distance from the mouthof the flue A, the lock-nuts c are turned up and the plate is locked inplace. By this construction, by loosening the locknuts 0 and turning theposts 0, the front plate B may, at any time, be adjusted at .anydesired: distance from the-mouth of the Having thus described my invention,l claim as new and desire to secure by Letters Patent- Thecombination of the posts 0, having a right screw-thread upon one end,and a left screw-thread upon the other end, the

nuts c 0 and the lock-nuts 0 with the front plate B, and the -fiue A,provided with a Weighted valve, D d, and a balance-cord,

E" e, substantially as herein shown and described.
